I've indeed upgraded to the latest version. I attempted doing it again just in case the files weren't overwritten the first time. Same deal.

I get a 500 server error when logging in (forgot to mention that yesterday since I was testing a lot). I can access the generator from either generator.example.com or example.com/generator, as I always have been able to, but when I log in I receive the 500 server error.

The sitemap updating itself actually still works when the cron fires every night; it's simply being able to change settings through the interface where things get broken.

Is there a way to do that outside of the interface? I looked through the documents and could only find methods of changing options when you're in the configuration via the PHP interface. Is there a specific file I can edit to change these details?
